<P>PROBLEM TO BE SOLVED: To provide a voice synthesizer having reduced memory size required for storing phonemes. <P>SOLUTION: A voice synthesizer includes: a storage device 14; a phase calculation section 32; and a voice synthesis section 34. The storage device 14 stores phoneme data D indicating an amplitude spectrum SM of each frame of a phoneme. The phase calculation section 32 calculates a minimum phase corresponding to the amplitude spectrum SM indicated by the phoneme data D, as a phase spectrum SP of the phoneme for each of the frames. The voice synthesis section 34 generates a voice signal VOUT, by utilizing the amplitude spectrum SM of each of the frames indicated by the phoneme data D and the phase spectrum SP of each of the frames after calculation with the phase calculation section 32. <P>COPYRIGHT: (C)2013,JPO&INPIT |
